Orthogonal frequency division multiplexing (OFDM) has become a prevalent and widespread technique for the broadcast and transmission of signals over wireless channels and has been adopted in many wireless standards. OFDM may be united with antenna arrays at the transmitter and receiver side to improve the diversity gain and to improve the system competence on time-variant along with the frequency-selective channels, resulting in a multiple-input multiple-output (MIMO) composition. | Performance analysis for PAPR reduction using SLM technique in 2 x 1 and 2 x 2 differential STBC MIMO RS OFDM systems in rayleigh fading channel
